ABSTRACT:
The invention concerns a conveyor belt scraper (10) which includes blade segments (12) each arranged to scrape a portion of the width of a conveyor belt (22). Each blade segment is supported by a bracket (14) which is mounted to a link (16.1) of a deformable, parallelogram linkage (16). An inflatable hose (30) extends through and acts on the linkages to urge the blade segments against the conveyor belt. The link has a projecting, holed boss (42) and the bracket has a recess (40.3) to receive the boss with the hole of the boss aligned with a hole in the base of the recess to receive a fastener (50) that connects the bracket to the linkage in thermally transmitting relationship. This relationship reduces heat degradation of components of the scraper.
